1ZR-FE FUEL FUEL INJECTOR INSTALLATION
PROCEDURE
23250 1.INSTALL FUEL INJECTOR ASSEMBLY
*1 | O-ring |
*2 | Injector Vibration Insulator |
Apply a light coat of gasoline or spindle oil to new injector vibration insulators and new O-rings, and then install one onto each fuel injector assembly.
Apply a light coat of gasoline or spindle oil where the fuel delivery pipe sub-assembly contacts each O-ring.
While turning the fuel injector assembly left and right, install it onto the fuel delivery pipe sub-assembly.
- NOTICE:
- ·
Do not damage the fuel injector assembly and O-ring.
·Do not twist the O-ring.
·After installing each fuel injector assembly, check that it turns smoothly. If not, replace the O-ring with a new one.
- HINT:
-
Use the same procedure to install the other fuel injector assemblies.
23807V 2.INSTALL NO. 1 DELIVERY PIPE SPACER
*a | Fuel Delivery Pipe Sub-assembly Side |
*b | Cylinder Head Sub-assembly Side |
Install the 2 No. 1 delivery pipe spacers onto the cylinder head sub-assembly.
- NOTICE:
-
Install the No. 1 delivery pipe spacers in the correct direction.
23807 3.INSTALL FUEL DELIVERY PIPE SUB-ASSEMBLY
Install the fuel delivery pipe sub-assembly with the 4 fuel injector assemblies with the 2 bolts.
- Torque:
- 21 N*m (214 kgf*cm, 15 ft.*lbf)
- NOTICE:
- ·
Do not drop the fuel injector assemblies when installing the fuel delivery pipe sub-assembly.
·After installing the fuel delivery pipe sub-assembly, check that the fuel injector assemblies turn smoothly.
Install the clamp to the cylinder head sub-assembly with the bolt.
- Torque:
- 21 N*m (214 kgf*cm, 15 ft.*lbf)
Install the wire harness bracket to the intake manifold with the engine cover joint.
- Torque:
- 8.0 N*m (82 kgf*cm, 71 in.*lbf)
23901 4.CONNECT FUEL TUBE SUB-ASSEMBLY
- NOTICE:
-
Check if there is any damage or foreign matter on the connecting parts of the fuel lines.
*a | Retainer |
*b | O-ring |
*c | Nylon Tube |
*d | Fuel Tube Connector |
*e | Fuel Pipe |
Connect the fuel tube sub-assembly to the fuel delivery pipe sub-assembly.
Align the fuel tube connector with the fuel pipe, and push them together until the fuel tube connector makes a "click" sound. If it is difficult to push the fuel pipe into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.
After connecting the fuel lines, check that the fuel pipe and fuel tube connector are securely connected by pulling on them.
Engage the 2 claws to install a new No. 2 fuel pipe clamp.
82121 5.CONNECT ENGINE WIRE
Install the 2 wire harness brackets to the cylinder head sub-assembly with the 2 bolts.
- Torque:
- 12.8 N*m (131 kgf*cm, 9 ft.*lbf)
Engage the 4 wire harness clamps to the wire harness brackets.
*a | 20° |
Engage the 2 wire harness clamps.
Connect the 4 fuel injector assembly connectors.
Connect the ground wire to the cylinder head cover sub-assembly with the 2 bolts.
- Torque:
- 8.4 N*m (86 kgf*cm, 74 in.*lbf)
- HINT:
-
It is acceptable for the ground wires to be tilted +20° to -20°.
